Summary:
Mario Kart 8 Deluxe just received a free 4.0.0 update that brings targeted improvements for the Nintendo Switch 2 while keeping compatibility with the original Switch. The headline features are support for the Nintendo Switch 2 display and high-resolution TVs, noticeably shorter loading times, new CameraPlay functionality using a compatible USB camera, and expanded local multiplayer with support for five to eight players on a single Switch 2 system. The patch also includes gameplay adjustments – such as a slight speed increase equivalent to one coin and changes to Boo invisibility – and a new 96-race option for players who own the Booster Course Pass. Whether you race locally with a crowd or want to see faces during matches online via GameChat, this update is designed to make sessions faster, clearer and more social for Switch 2 users while leaving core features intact for everyone else.
What Mario Kart 8 Deluxe Version 4.0.0 Changes and Why They Matter
This update, labelled version 4.0.0, focuses on practical improvements that affect both presentation and play. The technical side includes better support for the Nintendo Switch 2 display and high-resolution TVs, which results in crisper visuals when played on the newer hardware. Players on Switch 2 will also notice reduced load times – less staring at logos and more time on the track. On the social side, CameraPlay and expanded split-screen support alter how groups experience Mario Kart together, making it easier to host chaotic couch sessions with more people. Finally, there are small-but-meaningful gameplay tweaks – speed adjustments and Boo behavior changes – that slightly alter race dynamics. All of these updates aim to modernize the game for Switch 2 while keeping the pick-up-and-play spirit that made Mario Kart 8 Deluxe a staple.
Switch 2 Enhancements – Visuals, Load Times and Performance
For owners of the newer console, this patch provides tangible improvements that make Mario Kart 8 Deluxe feel fresher without being a full remake. The game now includes explicit support for the Nintendo Switch 2 display and high-resolution TVs, which translates to clearer, sharper visuals when the title runs on that hardware. Loading times before races and battles have been shortened so you get into races more quickly, which helps the flow when you’re hosting a party or doing back-to-back sessions. These are the kind of quality-of-life upgrades that don’t change how the game plays, but they do improve the overall experience and make long sessions less interrupted by waiting.

Eight-Player Split-Screen – How It Works and Controller Requirements
One of the most eye-catching changes is support for five to eight players in local multiplayer on a single Nintendo Switch 2 system. That means, with enough controllers, you can cram more people onto the same console for split-screen races – perfect for parties and family gatherings. The patch clarifies controller limits: you can connect up to seven standard Switch controllers (Joy-Con pairs or Pro Controllers) and, if you want to reach eight players, at least one Joy-Con 2 or a Nintendo Switch 2 Pro Controller is required. That specific requirement ensures the console can read the extra inputs and maintain a stable multiplayer session. Be mindful that accessories may be sold separately and you’ll want comfortable seating and a big TV for the full eight-player chaos to be playable and fun.
CameraPlay Explained – Using a USB Camera and GameChat
CameraPlay adds a social, face-forward element to races. With a compatible USB camera connected to a Switch 2, players can enable their camera so their face appears on-screen while racing locally or in online GameChat sessions. CameraPlay works in Multiplayer modes (two to four players) and Online Play when participants join a GameChat session; footage and microphone audio are shared only with members of that GameChat. A compatible USB camera is required and the feature can be toggled ON or OFF, giving players control over privacy. The effect is simple: you can see your friends’ reactions as they hit a banana or boost past you, which adds a layer of personality and real-time banter that text chat can’t match. Just keep in mind that GameChat, an internet connection and a Nintendo Switch Online membership may be required for certain online camera features.
Gameplay Adjustments – Small Changes That Shift Races
While most of the update is about platform enhancements, there are a few gameplay tweaks worth noting. Player speed during races has been increased by the equivalent of one coin, which subtly changes how top-end speed is reached and may affect tight time differences in competitive lobbies. The patch also makes it so players won’t slow down when using Boo to become invisible, even when passing through offroad sections, which changes how stealth and evasion can be timed. Additionally, players who own the Mario Kart 8 Deluxe – Booster Course Pass will see a new “96 Races” option added to the VS Race rule settings, letting you string together longer playlists for marathon sessions. These sorts of small adjustments rarely upend the meta overnight, but they can influence time trials and competitive runs, so expect leaderboards and lap times to see some movement.
Compatibility and Online Play Considerations
Version 4.0.0 is designed to be compatible across Switch generations, but some features are Switch 2 specific. Local split-screen expansion and CameraPlay are tied to the new hardware’s capabilities or to compatible accessories, so players on the original Switch will continue to play without those enhancements. It’s also important to remember that all players must use the same software version to play together online or locally; downloading the latest update is necessary if you want to join friends who have already updated. For online features using the camera and GameChat, an active Nintendo Switch Online subscription, a Nintendo Account and an internet connection are required. These requirements are standard for Nintendo’s online ecosystem, so make sure your membership and accounts are in order before trying the new online camera features.
How to Update and What You Need
Updating to version 4.0.0 is straightforward: from the HOME Menu, highlight Mario Kart 8 Deluxe, press the + or – button, then select Software Update and Via the Internet. If you’re running a Switch 2 and want to use CameraPlay, you’ll also need a compatible USB camera that’s sold separately. For eight-player local split-screen, gather up to seven additional controllers and ensure at least one Joy-Con 2 or a Switch 2 Pro Controller is present if you want to reach the eighth slot. The update itself is free, but accessories and DLC like the Booster Course Pass remain paid items. Make sure your console has enough free storage and that your Nintendo Account is active to download the patch and access all online features.
What This Update Means for Players and Parties
This update is a clear sign that Nintendo still sees value in supporting older titles with targeted improvements for new hardware, and fans of Mario Kart 8 Deluxe should appreciate the attention. Party hosts get more options for local multiplayer, streamers or social players can benefit from CameraPlay, and casual racers get slightly improved pacing thanks to shorter load times. Competitive players will want to keep an eye on how the speed change affects records and leaderboards, while DLC owners can enjoy longer VS Race playlists. If you’re a NintendoReporters reader, this is the kind of update that makes gathering friends for impromptu races even more appealing, and it keeps Mario Kart 8 Deluxe feeling modern without needing a full remake.
Conclusion
The 4.0.0 update for Mario Kart 8 Deluxe brings meaningful Switch 2-specific improvements – sharper visuals, faster load times, CameraPlay and expanded local multiplayer – while keeping the core game intact for everyone else. Small gameplay tweaks and the new 96-track VS Race option add variety, and the update demonstrates how a decade-old title can still evolve to take advantage of new hardware and social features. If you own a Switch 2, this patch is worth installing right away; if you don’t, the game remains largely the same but continues to receive careful support. Grab your controllers, check your camera and get ready for more chaotic racing sessions with friends.
